The cake is a lie!
It's an excellent key cap key chain from the acclaimed Portal video game series by Valve! The cake is a lie. But you still want it, don't you? So finally get it for yourself and put it on your keys! Or at least you can have the cake level sign on your keys, because that's what this is, just the square level sign of a piece of cake with a cherry on top. If you want actual cake, you're going to have to go somewhere else to get it. A bakery, perhaps. Any who, all tangents aside, buy yourself this excellent Portal Cake Level Sign Key Cap Key Chain and carry around a part of Aperture Science with you!
